Spring Vane Fluid Clutch

In step by step feeds such as for tape, it is desirable that each step be made as rapidly and evenly as possible. A resilient drive effects this action.

The clutch comprises a cylindrical shell of two members 10 and 11 provided with mating threads 12 which join them in a unitary oil tight structure. Formed on the inner periphery of each member 10 and 11 are vanes 14. Each member 10 and 11 is provided with journals for a shaft 15 formed with an enlarged mid- portion 16. A plurality of vanes 17 is mounted on the portion 16 by resilient posts
18. Member 10 is formed with a notch 20 to accommodate a belt 21 by which the shell is driven.

Rotational movement is transmitted from the vanes 14 to vanes 17 by fluid pressure. When the shaft 15 is stopped the resilient posts 18 bend and store up energy which, when the shaft 15 is released, transmits that energy to the shaft to overcome the inertia and effect a fast start.
